UNITED STATES PATENT OFFICE 1 Claim.

My present invention, in its broad aspect, has to do with improvements in washing machines for clothes, dishes, or any other objects, and one of the important objects is to provide a washin machine wherein no moving parts come into contact with the objects to be Washed, and wherein the cleansing action of the washing fluid is obtained by positive circulation of the fluid in, around and through the objects to be washed, such circulation being induced by an action simiiar to a pumpin action.

Another object of my invention is to provide a very simple and efficient device wherein the cleansing fluid is both agitated and pumped or circulated through the objects to be Washed, and to this end I provide a perforated false bottom in a container, wherein all of the objects to be washed are above the false bottom and all of the movable parts are below the false bottom and positively separated from the objects to be Washed.

Other and equally important objects and advantages of my invention are: (1) to provide a very simple and effective mechanism for both agitating and circulating or pumping the cleansing fluid (2) to provide a compartment for the objects to be washed absolutely free of any parts, projections or objects likely to come into contact therewith and which might injure or tear or otherwise disadvantageously affect such objects; (3) to provide a simple and effective operating mechanism, and (4) to provide a practical, economical, easily cleaned device which may be manufactured and sold at small cost and is adapted for household use.

Other objects and advantages will be apparent from the following description taken in connection with the drawings, but it is manifest that changes in form, size, shape, arrangement and construction of parts may be made without departing from the spirit of my invention or what is claimed.

In the drawings wherein I have illustrated a preferred form of my invention:

Figure 1 is a top plan view;

Figure 2 is a sectional side elevation taken on line 2-2 of Figure 1;

Figure 3 is a transverse section taken on line 33 of Figure 2, and

Figure 4 is a top plan view with the internal parts removed.

Figure 5 is a section taken on line 5-5 of Figure 2 showing the pitman connection at the lower end of the shaft.

In the drawings wherein like characters of 2 reference are used to designate like or similar parts throughout the several views:-

The numeral I designates a cylindrical, open top container having a bottom 2 with an outlet 3 having a stopper 4, and the container is provided with suitable legs 5. The container may be of galvanized sheet metal or the like, and if desired may have a removable lid of conventional construction (not shown).

Mounted within the receptacle or container I is a false bottom 6, upwardly flanged as at l, and having diametrically opposed radial pairs of rows of spaced openings 8. Fixed to the bottom 2 and sides of the container and positioned between the rows of the openings 8 of each pair are four diametrically opposed radial vanes or partitions 9, between the inner ends of which is a spider formed with a sleeve III havin four diametrically opposed radial vanes II. The sleeve is pinned or keyed to vertical shaft I2 extending up through the bottom 2. Shaft I2 has a bushing I3 on its lower end fitted in collar I4 providing a packing gland on the under side of the bottom, and is provided with a laterally extended end I t on which a swivel or universal socket I5 is pivotally mounted. A pitman I! is pivotally mounted in the socket I5 by a. pin Na, and the opposite end is rotatably mounted on a pin I8 and the pin I8 is carried by a crank I9-operative1y associated with the power plant or motor 20 to give the shaft I2 an arcuate oscillation about its vertical axis as the crank I9 is turned to reciprocate the vanes II in a similar manner between the partitions 9 whereby to circulate or pump the cleansing fluid (not shown) up and down through openings 8 in the false bottom 6 thereby to cleanse the objects placed in the container I above the false bottom. It will be noted that as vanes II approach vanes 9 on one side fluid is forced up through the openings 8 on that side, and drawn clown through the openings 8 on the other, with an action that resembles a pump. Suitable hand grip slots 2| are provided in the flange I of false bottom 6 to facilitate removal of the same from the container I, and the power plant I8 is mounted on a support bracket 22 which may be carried by one of the legs 5.

It is believed that the operation and advantages of my invention will be apparent from the foregoing, but in visualizing the broad inventive concept and interpreting its scope, reference is to be had to the appended claim.

I claim:

In a washing machine, the combination, which comprises, a vertically disposed cylindrical casing,

a false bottom having pairs of rows of perforations therein spaced from the lower end of the casing providing a lower compartment therein, and removabl mounted in said casing, radially disposed partitions in the said lower compartment of the casing positioned between the rows of perforations, with one row of perforations of a pair on each side of each partition, a, spider having a sleeve with a plurality of vanes extending therefrom rotatably mounted in the said lower compartment and with the vanes positioned between the said partitions, and means oscillating the said spider, wherein the said vanes squeeze water in the areas between the vanes and partitions upwardly through the rows of perforations of the false bottom on one side of each of said partitions 4 as the vanes approach the partitions and draw water downwardly through the perforations behind the vanes.
